Why do windows in the apartment sweat?

The problem of foggy windows is known to everyone firsthand. We will deal with the nature of the phenomenon and consider the solutions.

Fastened windows are the result of condensate formation, a product of the transition from a gaseous state to a liquid form when cooling the substance.

The parameters on which the formation of condensate depends:

atmospheric pressure;

air temperature;

humidity.

To eliminate the likelihood of condensation, it is necessary to reduce humidity and raise the air temperature.

Why do the windows sweat, and how to fight

1. The natural ventilation system does not work well or does not work at all. It will solve the problem of cleaning the ventilation shaft and the organization of additional supply valves – passive devices that provide an air flow.

2. Cold from slopes and walls.

Insulate the slopes and, preferably, external walls.

3. Dampness in the room is a disease of the first and last floors.

Good thermal insulation of the floor on the ground floor and the ceiling on the last helps.

4. Low -quality, poorly isolated double -glazed windows, or windows were installed in violation of the technology.

Use the services of professionals, contact the installers to eliminate shortcomings. Energy -saving glasses, an argon filling, 2 -chamber double -glazed windows or a plastic frame in them, instead of an aluminum, a narrow windowsill that does not block the batteries – effective measures against fogging windows.

5. Wooden windows provide an air flow even in a closed state. Closed plastic windows pass air 5-10 times less than normal, as a result, violation of the process of natural ventilation.

The problem is solved by constant ventilation of the room.

Useful tips

We analyzed the private reasons why the windows in the apartment are sweating, but in addition to avoid condensate, there are a number of general recommendations:

The number of plants should be reduced;

Choose the correct, breathing finish inside the house, give preference to natural materials;

repair plumbing;

Wet cleaning should end with dry wiping;

Buy devices that drain air and automatically normalize humidity;

Do not turn off the heating in the cold season;

Increase windows heating by installing a more powerful battery;

In order not to sweat the window in the apartment, either do not allow cooling the glasses to the level of the dew point, or lower the humidity in the room to the norm. As a rule, these two methods together solve the problem.
